Notice of RetractionFEA and optimize design of a new type structure of FOG

Fiber-optical Gyroscopes (FOG) is becoming affordable for many applications such as vehicle navigation and stabilization. Environmental impact of vibration can't be ignored. This paper researched into the characteristic of vibration of structure of FOG. Base on the model analysis using ANSYS WORKBENCH (finite element analysis software), we did dynamic analysis for structure of FOG. On the model analysis, we got the frequencies and model shapes of bracket. On the harmonic response analysis, we got the curves of frequency response. We analyzed the frequencies and model shapes of bracket. At last, we brought forward the methods to optimize the framework design of FOG, and designed a new type structure.
